windows defender doz NOT detect cookies (as spyware). it choses to ignore them; but its good enuf - though it was rankd rather low in one of the recent comparatives...
downloading free screensavers and installing them is the best way to get FREE spyware

. i m sugsting this to u since u have mentioned that u ARE going to reinstal in 2 days. so no harm learning first hand. porn/xxx/crack sites too will oblige u with free malware, btw !
